where do I get one of these

he priced it to me at $385.00. I just found a OEM replacement 2 row for $167.50 shipped. I may just go with that. I just like 3 rows though. I have a 4 row in my Duster but this engine isnt gonna be nowhere near what I have in the Duster. It is a stock 360 but we plan on building the 340 some so that is why I wanted a 3 row.
